Application iled October 19, 1901. Serial No. 79,215. (No model.)

' 1'0 LLA wtont it 17ML!! concern:

Be it known that I, RALPH V. SAGE, a citizen of the United States,residing at Johnstown, in the county of Cambria and State ofPennsylvania, have invent-ed certain new and useful Improvements inTruck-Holsters, of which theA following is a specification.

This invention relates to truck-holsters, and particularly to holstersfor heavy vehicles or vehicles adapted to carry heavy freight andespecially steel gondola cars, and has for its object to provide animproved bolster of the class described which will possess advantages inpoint of convenience, inexpensivenesmeffectiveness, and generaleihciency.

Another object of my invention is to provide au improved bolster of theclass described the parts of which shall be ordinary merchantable forms,and therefore easily, readily, and inexpensively procured, and which canbe assembled without difficulty by ordinary mechanics, and which areparticularly adapted to resist Vthe strains to which such bolster isliable and when assembled will constitute a bolster equal to any now inuse in strength, durability, and adaptability to the requirements ofsuchY a device.

In the drawings, Figure 1 is a plan view ofabolsterembodyingmyimprovements. Fig. 2 is a side elevation of the same.Fig. 3 is an end elevation of the 'samel Fig. 4 is a sectional view online a; x, Fig. 1.

Corresponding parts in all the iigures are denoted by the same referencecharacters.

Referring to the drawings, my improved bolster comprises, in general,two I-beams having the iianges on the outside cut away for a distance ateach end, two channels secured a short distance apart back toback-between the I-beamsl at the center of the'bolster, said channelsadapted to receive the king-pin between them,amal1eable casting securedbetween the ends of said I-beams and adapted to receive thebolster-springs, and plates secured on the outside of the ends of theI-beams to form guides for the truck-columns.

In the forms shown in the drawings, and whicl1 if desired, may bethepreferred form, my improved'bolster comprises two I-beams l, placedside by side at a suitable distance apart. The flanges of the beams l onthe o utside, at each end on both sides, are cut away from the end for ashort distance, and a pair of plates 2 are secured at a suitabledistance apart to serve as a guide for one of the truckcolumns (notshown) on each side of each end of the pair of beams l in'any suitablemanner, herein shown on rivets 3. Between the ends of the beams 1 aresecured malleable castings 4, which reston the bolstersprings. (Notshown.) The castings 4 may, if desired, extend up to and restagainst thetop inside iianges of the beams 1 and be provided at the bottom withlugs 5 to take the bolster-springs. (Not shown.) About midway of thelength of the beams 1 and at a suitable distance apart to receive theking-pin (not shown) between them two channels 6 are secured back toback and with their -iianges vertical between the beams l in anysuitable manner, herein shown as rivets 7, passingjthrough the ilangesof the channels 6 and the webs of the beams 1. Brake-hanger castings 8are secured to the webs of the beams l, preferablyv where the cut-awayportion of the iiange's of the beams 1 ceases,inanysuitable'manner,'herein shown as rivets 9.

The operation and advantages of my invention will be readilyunderstoodaud appreciated. The I-beams 1, 'positioned as they are in myimproved bolster, offer the greatest possible resistance to strain intheV direction such bolster receives it for the amount of metal used,and the channels 6 likewise form the best possible means of reinforcingsaid beams l at the point of greatestweakness. If the castings 4 areextendedup to and rest against the top flangesof the beam 1, the saidflanges will then serve as additional means of securing said castings 4in place. Moreover, all the parts except the castings 4'are ordinarymerchantable forms easily procured in the open market and not-requiringspecial machinery for their production.` i The castings 4 are simple andless expensive thanthe bent plates now used. Then theorganization of theparts, while producingasimple, strong, and durable bolster, as good asany now in use, is such that the assemblage of them can be done by anyordinary mechanic.

I do not desire to be understood as limiting myself to the details ofconstruction and arrangement as herein described and illus- IOO .trated, as it is manifest that variations and modifications may be madein the features of construction and arrangement, in the adaptation ofthe device to various conditions of use Without departing from thespirit and scope of my invention and improvements. I

thereforefreserve the right to all such variation and modification asproperly fall within the scope of my invention and the terms of thefollowing claim.

Having thus described my invention, I claim and desirefto secure 'byLetters Patent- An improved bolster ofthe class described, comprisingtwo I-beams parallel to each other, having their outside anges at theends cut RALPH v. SAGE.
